I tried to remove a Quick Note from OneNote in my Lumia 525 Windows Phone by long pressing a Quick Note and I found two options. One is Pin to start and another one is Delete. But that delete option is invisible so I was not able to delete a Quick Note. I tried marking and deleting but at that time also delete option is invisible. Is there any alternative way to delete a Quick Note? Does it is an issue with my mobile or with Windows 8.1 OS? See the screen shot for clear understanding.
